TPMT 16T308 T9225 — ISO triangular turning insert for medium to heavy steel by Tungaloy

TPMT16T308-24 T9225 is an ISO-standard turning insert engineered for medium to heavy steel turning, offering a robust CVD-coated carbide grade for variable cutting conditions

• CVD-coated carbide T9225
• Robust universal grade for medium-heavy steel
• ISO triangle 60° form
• Cylindrical hole with 40°–60° countersink

High-performance turning for mixed steel applications

The TPMT16T308-24 T9225 insert combines a CVD-coated surface with a tough carbide substrate to balance wear resistance and fracture toughness. This composition supports stable cutting during external and internal turning where entry conditions vary or cuts are intermittently interrupted. The coating reduces flank wear under continuous engagement while the substrate provides the necessary edge stability during transient loads. For shops processing batches of alloyed and carbon components, this grade maintains surface quality and extends the interval between indexings compared with uncoated or softer grades.

Seamless integration with ISO tooling systems

As an ISO-standard triangular insert, the geometry with an included angle of 60° and a corner radius of 0.8 mm radius is compatible with many indexable holders provided key parameters match: form, 11° relief angle, tolerance class, fastening and 3.97 mm thickness. The insert’s cylindrical hole with a single-sided countersink (40°–60°) ensures secure seating and repeatable clamping. These defined interfaces simplify tool selection and reduce setup time, enabling predictable alignment and consistent contact between insert and holder for reproducible results across machines.

Operational gains: fewer tool changes, consistent surface quality

Selecting the T9225 universal grade and the insert’s chipbreaker designation (24) is aimed at increasing process reliability under changing conditions. The grade’s emphasis on toughness supports machining strategies that would otherwise require more frequent tool changes, thereby improving overall productivity. Stable chip formation and reduced risk of edge chipping contribute to uniform workpiece finishes, which in turn minimise rework. For production contexts where uptime and repeatability matter, this grade helps maintain cycle times while protecting downstream operations from variable surface integrity.

Practical recommendations for best results

For optimal performance, match the chipbreaker and grade to the workpiece material and rigidity of the setup; lighter, rigid set-ups favour higher cutting speeds, while less stable configurations benefit from the grade’s enhanced toughness. Use a suitable external holder or boring bar designed for triangular ISO inserts and ensure the clamping torque and seat cleanliness are correct before cutting. Coolant application and conservative initial depths of cut are advised when encountering unknown material variations; adjust feeds and speeds based on observed wear patterns and chip form to fully exploit the insert’s stable chip formation and wear-resistant coating.

FAQ

What materials is this insert suitable for?
The TPMT16T308-24 T9225 insert is intended primarily for medium to heavy steel turning; the Tungaloy T9225 grade provides the required toughness for variable engagement and lightly interrupted cuts.

What does the ISO designation 16T308 indicate?
The ISO code denotes the insert’s geometry and size: triangular form with specific seat and corner characteristics. The TPMT16T308-24 T9225 follows ISO standards to ensure proper fit in compatible holders.

Can this insert handle interrupted cuts and variable entry conditions?
Yes — the CVD-coated carbide grade T9225 has been developed for robust performance under interrupted cuts and changing machining conditions, reducing the risk of edge fracture.

How is the insert mounted in the holder?
The insert uses a cylindrical hole with a single-sided countersink (40°–60°) for secure clamping; fitting requires a compatible triangular ISO holder with matching seat and clamping hardware.
